Fleet Safety FAQ

What is a CSA score, and why does it matter for my fleet?

CSA stands for Compliance, Safety, Accountability — FMCSA's Safety Measurement System (SMS) program that uses inspection, crash, and violation data to generate safety percentile scores for carriers.

Scores are organized by seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator. A higher percentile score in any BASIC indicates a higher proportion of violations relative to other carriers in your peer group.

Carriers with scores above threshold percentiles in certain BASICs may be flagged for investigation or intervention. For small fleets, a single roadside inspection with violations can move a percentile significantly.

That makes consistent pre-trip inspections and driver coaching documentation among the most practical ways to manage SMS exposure.

What is a nuclear verdict, and how does it affect small trucking companies?

A nuclear verdict is a civil jury award significantly above what most observers would consider proportional to the actual damages — commonly defined in trucking as verdicts in the tens of millions or higher.

They're not common in absolute terms, but they've become a significant risk management topic in the industry because the trucking sector has seen a meaningful number of them over the past decade. For small carriers, the concern is less about the probability of a specific verdict and more about what factors tend to contribute to them: inadequate safety documentation, driver coaching records that don't exist or aren't credible, post-incident response that looks disorganized or evasive, and fact patterns that suggest systemic neglect rather than a one-time error.

A carrier with solid documentation, consistent coaching records, and a clear post-accident process is in a materially different position than one without those elements, regardless of what happened at the scene.

What records does FMCSA require carriers to keep after an accident?

15, carriers are required to maintain an accident register for three years.

5 — those involving a fatality, bodily injury with the injured person receiving medical treatment away from the scene, or one or more vehicles incurring disabling damage and requiring a tow. The register must include the accident date, city or town and state, driver name, number of injuries, number of fatalities, and whether a hazardous material spill occurred.

Carriers must also make this register and copies of any accident reports available to FMCSA or an authorized state or local enforcement officer on request. This is a minimum requirement — your insurer and company policy may require additional records and longer retention periods.

How long should I keep fleet safety records?

Retention requirements vary by record type and are set by a mix of federal regulation, insurer requirements, and state law.

401). Your insurer may require longer retention periods for records connected to claims or incidents that could produce future litigation.

When in doubt, retain longer rather than shorter — the cost of storage is far lower than the cost of a missing record in a contested claim.

What should a small fleet safety policy include?

A useful fleet safety policy doesn't need to be long, but it should cover: incident reporting requirements (who to call, when, in what form), accident documentation steps, dash cam and evidence preservation procedures, post-accident testing criteria and process, driver coaching protocols, vehicle inspection expectations, and the consequences for safety policy violations.

' The policy should be distributed to every driver before they operate a company vehicle, and drivers should sign an acknowledgment that they received and reviewed it. That acknowledgment is part of the safety file, not just a formality.

What is a DOT roadside inspection, and how should drivers prepare for one?

A DOT roadside inspection is a compliance check conducted by a CVSA-certified inspector — typically a state trooper or motor carrier enforcement officer — at a roadside location, weigh station, or truck stop.

Inspections check driver credentials (CDL, medical certificate, hours-of-service records), vehicle condition (brakes, tires, lights, securement, fluid levels), and regulatory documentation (registration, operating authority, hazmat placarding where applicable). Drivers should know where their documents are before they're asked.

A driver who can produce their CDL, medical certificate, and current ELD records quickly and without searching makes the inspection faster and less likely to result in additional scrutiny. Out-of-service violations — those serious enough to prohibit the driver or vehicle from continuing — affect CSA scores and may trigger follow-up investigation.

How does driver coaching documentation protect a fleet in litigation?

Coaching records serve two purposes in litigation: they demonstrate that the fleet took safety seriously and acted on identified risk, and they establish what the driver was expected to know and do.

A fleet that has a coaching record showing a driver was counseled on following distance three months before a rear-end crash is in a different position than one that has no coaching history at all. The coaching record doesn't guarantee a favorable outcome — nothing does — but it shows the fleet was engaged in active safety management rather than passive operation.

Coaching records should include the date, what event was reviewed, what was discussed, what the driver acknowledged, and who conducted the review. A form that's actually filled out is better evidence than a policy that exists but wasn't applied.

What is an accident review board, and do small fleets need one?

An accident review board is a structured internal process for reviewing incidents and classifying them — typically as preventable or non-preventable — based on the full available evidence.

For large carriers, this is usually a standing committee. For small fleets, it's often a documented review process involving the safety manager and, where appropriate, operations leadership.

The value of the process isn't in the classification itself but in the discipline it creates: a consistent review with a written record, conducted within a defined timeframe, that documents what evidence was reviewed, what conclusions were reached, and what follow-up action was taken. That paper trail is useful if the incident is later contested.

An 'accident review board' for a 10-truck fleet can be one person with a form — as long as the review actually happens and the form gets filled out.

What's the difference between FMCSA enforcement and an insurance audit?

FMCSA enforcement comes from regulators — federal or state commercial vehicle enforcement officers — and focuses on compliance with Federal Motor Carrier Safety Regulations.

Findings can result in penalties, safety ratings changes, or in serious cases, operations orders. An insurance audit is a process conducted by or on behalf of your insurer — sometimes annually, sometimes triggered by claim activity — that reviews your safety practices, driver qualifications, vehicle maintenance records, and loss history to assess risk and confirm coverage terms.

Both may request similar records, but they serve different purposes and have different consequences. Good recordkeeping helps with both: a carrier who can quickly produce clean, current records in either context is in a better position than one who has to reconstruct documentation under pressure.

How does post-accident drug and alcohol testing work?

303.

The regulation specifies which crash circumstances require testing and sets time limits: alcohol testing must be completed within 8 hours of the accident, and controlled substance testing must be completed within 32 hours. If testing isn't completed within those windows, the carrier must document the attempts made.

The regulation also describes what happens if the driver refuses. Fleets should have a clear post-accident testing protocol that drivers know before an incident — including which crashes trigger testing, who to contact, and where testing occurs.

Trying to figure out the protocol in the hours after a serious crash, under stress, is not the right time to be looking it up.
